declarative memory needs three things?
- lot so repetition
- dependent on medial temporal lobe
- lots of sleep
episodic memory def:
things that we did
ie of episodic memory
i went to a fundraiser last night
semantic memory
common knowledge facts/figure not based on personal experience
example of semantic memory
the frontal lobe is in the front of your brain
procedural memory is what type of memory
implicit
def of procedural memory
motor memory that you can do but you can’t necessarily explain them
procedural memory needs a lot of
repetition
sleep
learning happens where/
the frontal lobe
how does the parietal lobe help procedural memory?
it feeds in sensory info about our surroundings
how does the basal ganglia help procedural memory?
it has the motor loop - so
how do you test the associative stage?
the walky talky test:
can a person walk and talk at the same time/ do two things at once
list the three stages of procedural memory?
- cognitive
- associative
- automatic
cognitive stage is the
what to do
associative stage is the
how to do it
automatic stage is the
do it part
proceduarl memory involves three things:
learning
storage
adjustment to environmental changes
what structures affect learning?
frontal cortex
parietal cortex
basal ganglia
what structures affects storage
supplementary motor area
basal ganglia
adjustment to governmental changes involves what structures?
cerebellum
parietal cortex
motor cortex
declarative memory dsfx is
amnesia
two types of amnesia are
retrograde
anterograde
retrograde amnesia is
lose of old memories
anterograde amnesia is
can’t make new memories
which amnesia is more common
anterograde > retrograde
is the location the same for declarative and procedural memory?
NO : stored in different locations of the brain
can you dx declaratie and not proceduarl memory and vice versa
yes because stored in different areas of the brain
limits of attention mean?
that if information that is not attended to is not processesd
orienting is
the ability to lcoate specific sensory stimuli from many
divided attention is actually
switching attention
ability to switch back and forth between two tasks
consciousness and level of arousal are from
the reticular formation
therapy to increase attention?
keep it fun and interesting
get lots of sleep
therapy for orientating?
stimulus starch environment that you grade to add more distractions
example of orienting
ability to find the stop light when driving
example of divided attention
looking at a stoplight then the car next to you and then back at the road
selective attention
can attend to one stimulus that is most important: block out other stimulus
therapy for selective attention
find a quiet place/ sanitize the environment
sustained attention
ability to continue an activity over time
what makes sustained attention harder?
when its not interesting or meaningful
and you are fatigued
therapy for sustained attention?
meaningful fun engagement and if fatiguing you need to have fun bursts of a break
goal directed behavior loop is located where?
the first one so at the hairline
lat prefrontal on the pic
divergent thinking occurs at what loop
goal directed behavior loop
what is divergent thinking?
if one of our planned steps doesn’t work out – we have a plan to do something else
dx of divergent thinking looks like?
a “one track” mind
- can only do one thing
dx in the goal directed loop looks like:
trouble w/ goal setting and steps to do that goal
more ideational dx
goal direct behavior loop looks focuses on
figuring out what you want to do
steps needed to get to that goal
the emotional loop goes where?
the forehead
medial prefrontal on the pic
the second one
the emotional loop focuses on
generating
perceiving
fx of the emotional lop
- motivation
2 integrate emotions with facial response - helps us make predications
- reward seeking behavior
emotional loop communicates with
the primal brain
the emotional loop has what NT
dopamine
dopamine affects what loop?
the emotional loop since its the reward seeking loop
emotional liability is
abrupt mood swings
involuntary inappropriate emotional response
emotions are crucial for
sound judgements
somatic -maneuver hypothesis is
that you primal brain communicates with your working rationale brain and it gives you non conscious evaluation of a situation
and influences action
somatic-marker hypothesis short hand is
a gut feeling about something
social behavior loop is located where?
the third one so
the eyebrow area
ventral prefontal on pic
fx of the social loop
- guides behavior
- inhibits undesirable acitivity
3 elict autonomic activity
things that the social loop helps us with
recognizes social disapproval
regulates self control
selects relevant form irreleveant
dx to what structures affects the somatic marker
orbitofrontal cortex
dx to ortitofrontal cortex may
reduce control over undesirable behaviors
somatic marker provides link betwen
amygdala (threat sensor)
dorsolateral prefrontal cortex (rational)
dorsolateral prefrontal cortex does what?
raional, planning, goal-oriented
amygdala does what?
emotional
impulsive
immediate gratification
rational part is
action
selection system
(“social)
impulsive immediate part is
rewards seeking system (primal)
when you have dx to the ventral prefrontal
- disinhibition
- lack of concern about consequences
- impulsiveness
- inappropriate behaviors
- emotional liability
when you have dx to the ventral prefrontal you also dx the
somatic marker
the somatic nervous system –
increases muscle tension
autonomic nervous system
shunts blood from skin & gut to muscles
endocrine system (adrenal medulla)
epinephrine enhances cardiac fx, relaxes intestines, increases metabolic rate
